5 Five Balas (Five Powers)
The essential elements of the five Powers are the same as those
of the five Faculties. It should be understood that each of these
five elements has two distinct properties: 1) the ability to control
the mind, and 2) the ability to be firm and unshakable by the
opposing force.
1 Saddhà-bala – faith or confidence,
2 Vãriya-bala – energy or effort,
3 Sati-bala – mindfulness,
4 Samàdhi-bala – concentration,
5 Pa¤¤à-bala – wisdom.
In practice, saddhà and pa¤¤à should balance each other,
because too much faith leads to unreasonable belief and too
much investigation leads to no concentration.
Similarly vãriya and samàdhi should balance each other,
because too much effort may lead to restlessness and too much
concentration may lead to drowsiness.
Sati need not be balanced by any factor; the more sati there
is, the better it is.
